BACKGROUND

1. Field of Invention

The present invention relates to a display device.

2. Description of Related Art

In recent years, owing to the rapid development of the electronicsindustry and the information industry, the related products are alsoincreasingly sophisticated. For the current personal computers, inaddition to seek more rapid and more powerful computing units and a widerange of peripheral equipments to meet user needs, the compact sizedportable computers are also the key area of development of theindustries.

For example, liquid crystal displays have advantages such as highdefinition, small size, light weight, low driving voltage, low powerconsumption, and wide range of applications, so they can be widelyapplied in portable televisions, mobile phones, camcorders, notebookcomputers, desktop monitors, and other consumer electronics products andbecome the mainstream of the displays.

A display device applied in a notebook computer mainly includes a coverand a display module. The display module includes a first side and asecond side, wherein the first side includes a display region and thesecond side is adjacent to or mounted to the cover. With differentdesigns of products, the cover not only can be made of plastic andformed to be thin shell by injection molding but also can be made ofmetal (such as aluminum) and formed to be thin shell by stamping. Thedisplay module thus can be mounted with the cover to form the displaydevice. Besides, in order to mount the display device to the base, thedisplay device can include a hinge.

Generally, the hinge is pivotally connected to the hinge module on thecover. The hinge module is commonly mounted to the cover by fasteningwith screws. The hinge module not only can be used to be pivotallyconnected to the hinge but also can be used to mount and support thedisplay module. In other words, the display module and the cover can bemounted to each other by fastening the hinge module to the sidewall ofthe display module.

However, because the hinge module is fastened to the cover by screws,the thickness of the whole display device cannot be decreased. Inaddition, because the hinge module is fastened to the sidewall of thedisplay module, the hinge module must be substantially perpendicular tothe cover, which also makes the thickness of the display device hardlyto be decreased.

FIG. 1 is a front view showing a display device according to anembodiment of the invention. FIG. 2 is a back view showing the displaydevice. in FIG. 1. FIG. 3 is an exploded view showing the display devicein FIG. 1. The structures of the invention can be applied to a displaydevice that has backlight or a display device that does not havebacklight (i.e., the display device that actively emits light). Thedisplay device that has backlight can be a LCD (Liquid Crystal Display)device. The display device that does not have backlight can be an OLED(Organic Light-Emitting Diode) device. Although the following embodimentof the structures of the invention is applied to a display device thathas backlight, but the scopes of the invention will not be limitedthereby. Please refer to FIG. 1 to FIG. 3, the display device 100 of thefirst embodiment includes a cover 110, a frame 120, and a panel module,wherein the panel module includes a glass module 130 and a backlightmodule 140. The frame 120 can be mounted to the cover 110, and the panelmodule can be fixed to the frame 120 along a direction to form a displaymodule. The direction is the normal vector of the display region 132 onthe display module. When the display device 100 is a display device thathas backlight, the display module is a display module that hasbacklight. The display device 100 in the embodiment can be applied in anotebook computer, and the display device 100 can be pivotally connectedto a host (not shown) of the notebook computer with the hinge 110 aillustrated in FIG. 3. In other embodiments, the display device 100 canbe applied to electronic devices such as a tablet computer, a mobilephone, a television, and etc.

Please refer to FIG. 4. FIG. 4 is a partial and sectional view showingthe display device in FIG. 1. The cover 110 of the embodiment has a baseplate 112 and a sidewall 114. A supporting member of the frame 120 isprotruded inward, and the supporting member includes a first supportingportion 122 and a second supporting portion 124. The first end 122 a ofthe first supporting portion 122 is engaged to the sidewall 114 of thecover 110. The second supporting portion 124 is connected to the secondend 122 b of the first supporting portion 122 and leans or does not leanthe base plate 112 of the cover 110 depending on the needs of productdesign. The glass module 130 is fixed to the first supporting portion122 along a direction, and the backlight module 140 is disposed betweenthe glass module 130 and the base plate 112 and fixed to the secondsupporting portion 124 along the same direction, wherein the directionalong that the glass module 130 and the backlight module 140 are fixedto the frame 120 is the normal vector of the display region 132 on thedisplay module. With the needs of product design, the first supportingportion 122 is located on the frame 120 at a position outside that ofthe second supporting portion 124, so the light can be totallytransmitted to the glass module 130 from the backlight module 140. Anopening can be formed at the center of the frame 120, and the lightgenerated by the backlight module 140 can be transmitted to the glassmodule 130 via the opening so as to increase the brightness of thedisplay region 132. When the panel module is fixed to the frame 120, theframe 120 can surround the periphery of the panel module, and the panelmodule must cover the opening to increase the brightness of the displayregion 132. With the needs of product design, the frame 120 can furtherinclude a retaining portion 126 for preventing the glass module 130 fromleaving the first supporting portion 122 and for protecting the glassmodule 130. If the frame 120 does not include the retaining portion 126,the invention can further include a decorative frame 190 illustrated inFIG. 3. The decorative frame 190 is located at the periphery of theglass module 130 and engaged to the frame 120 or the cover 110 toprotect the glass plates of the glass module 130 from breakage whilebeing impacted. The glass module 130 includes a first side and a secondside. The first side of the glass module 130 includes the display region132 and is used to contact the retaining portion 126 or the decorativeframe 190. The second side of the glass module 130 contacts or is fixedto the backlight module 140. The panel module also includes a first sideand a second side, wherein the first side of the panel module is thefirst side of the glass module 130 and includes the display region 132.The second side of the panel module is fixed to the frame 120, so as tocombine the panel module and the frame 120 to form the display module.The first side and the second side of the panel module are two planes inparallel with each other.

Under the configurations that the frame 120 has the retaining portion126, the glass module 130 and the backlight module 140 of the panelmodule are both fixed to the frame 120, the frame 120 is engaged to thecover 110, and the glass module 130 is retained by the retaining portion126, the assembly of the display module can be accomplished. Because thedisplay module is mounted to the cover 110 without screws, the cover 110does not need to provide space to be fastened by screws so as to have athinner thickness and the display module does not need to be formedscrew holes so as to have a larger display region 132 (as shown in FIG.1 and FIG. 3). When the glass module 130 and the backlight module 140 ofthe panel module are just fixed to the frame 120 to form the displaymodule, the frame 120 is the only structure that provides support.Thereby, the display module and the cover 110 can be combined to eachother to form the display device 100 with the assistance of the supportof the frame 120.

In the embodiment, the first supporting portion 122 and the secondsupporting portion 124 can be made of plastics that have bufferingeffect, so as to provide support to the glass module 130 and thebacklight module 140. The retaining portion 126 can be made of rubberand integrally formed with the first supporting portion 122 and thesecond supporting portion 124 by co-injection molding. The cover 110 ofthe embodiment can be made of metals such as aluminum or other propermetals. But the invention will not be limited thereby. In otherembodiments, the cover 110 can also be made of plastics and haveintegrally formed reinforcing ribs or metal members for improvingstructural strength.

As shown in FIG. 4, the first supporting portion 122 of the embodimenthas a first supporting surface 122 c, and the second supporting portion124 has a second supporting surface 124 a. The distance between thefirst supporting surface 122 c and the base plate 112 is longer thanthat between the second supporting surface 124 a and the base plate 112.The orthogonal projection of the peripheral part 134 of the glass module130 on the base plate 112 and that of the backlight module 140 on thebase plate 112 do not overlapped to each other. Therefore, the glassmodule 130 and the backlight module 140 that are stacked to each otherare respectively fixed to the first supporting surface 122 c and thesecond supporting surface 124 a, wherein the glass module 130 is fixedto the first supporting surface 122 c with the peripheral part 134, andthe glue applied between the panel module and the frame 120 includesepoxy.

Besides, the sidewall 114 of the cover 110 has a first fixing portion114 a, the first supporting portion 122 on the frame 120 has a secondfixing portion 122 d, and the cover 110 can be mounted to the frame 120by making the first fixing portion 114 a and the second fixing portion122 d to be engaged to each other. After the cover 110 is mounted to theframe 120 to form the display device 100, the position of the cover 110is adjacent to the second side of the panel module, and the cover 110and the frame 120 both provide support to the panel module so as toimprove the structural strength of the display module. After the cover110 is mounted to the frame 120, the sidewall 114 of the cover 110 willcover the sidewall of the frame 120 to avoid light leakage of thedisplay device.

As shown in FIG. 4, when the display device 100 that has backlight is aliquid crystal display device, the glass module 130 of the firstembodiment includes a first glass plate 136, a liquid crystal layer 137,and a second glass plate 138. The first glass plate 136 is located atthe second side of the panel module and fixed to the first supportingportion 122, and the liquid crystal layer 137 is disposed between thefirst glass plate 136 and the second glass plate 138. The second glassplate 138 is located at the first side of the panel module forcontacting the retaining portion 126 or the decorative frame 190. Thefirst glass plate 136 and the second glass plate 138 can be made oftransparent materials with high strength, so as to protect the liquidcrystal layer 137 and make the light emitted by the backlight module 140suitable to be transmitted to the liquid crystal layer 137 through thefirst glass plate 136. Finally, after the liquid crystal layer 137processes the light, users can watch the images displayed by the displaymodule through the second glass plate 138.

As shown in FIG. 5 which is a stereoscopic view showing the cover of theinvention. The cover 110 of the invention can further include a hingemodule 106. The hinge module 106 mainly includes a bracket 106 a and apivotal portion 106 b. The bracket 106 a of the hinge module 106 can befixed to the inner surface of the cover 110 by glue 2, wherein the innerside of the cover 110 is adjacent to the second side of the displaymodule and the glue 2 includes epoxy. The pivotal portion 106 b of thehinge module 106 can be connected to the bracket 106 a. The hinge 108can be pivotally connected to the pivotal portion 106 b. Therefore, thehinge 108 can be mounted to the cover 110 by the hinge module 106 thatis fixed to the cover 110. With different designs of products, thepivotal portion 106 b and the bracket 106 a of the hinge module 106 canbe mounted to each other by a fixed method, which is a thermal bindingmethod, a screw fastening method, or a riveting method, so as to makethe pivotal portion 106 b able to pivotally connect the hinge 108. Inorder to provide enough mounting strength to the hinge 108 when thehinge 108 is forced in operation, the pivotal portion 106 b and thehinge 108 are generally connected to each other by the screw fasteningmethod. Generally, the bracket 106 a is adjacent to but does not contactthe second side of the panel module, so as to prevent the display devicefrom the defeat of white spots after being assembled.

It can be seen that because the hinge module 106 is mounted to the cover110 by gluing the bracket 106 a to the cover 110, the thickness of thehinge module 106 in the display device 100 (i.e., the space between thecover 110 and the display module) is equal to the thickness of thebracket 106 a. The length of screws that are applied to mount the hingemodule 106 to cover 110 in prior arts is about 4 mm, so the thickness ofthe display devices in the prior arts cannot be reduced effectively.Relatively, the bracket 106 a of the hinge module 106 of the embodimentis plate-shaped, and a range of the thickness of the bracket 106 a isonly 0.8 mm-1.0 mm. Therefore, the bracket 106 a that is fixed to thecover 110 will not influence the whole strength of the display device100 and can easily reduce the thickness of the display device 100.

As shown in FIG. 5, the cover 110 of the display device 100 of theembodiment can further include four rims 100 a, and the rims 100 a canbe classified to be two pairs and surround the cover 110. Generally, thetwo pairs of the rims 100 a can be classified into long rims and shortrims, and each pair of the rims 100 a are parallel to each other. Thebracket 106 a of the hinge module 106 can be substantially parallel tothe rims 100 a, and the rims 100 a are generally, but not limited to,the short rims and can be elastically changed according to therequirements of designing or limitations of manufacturing. Because thehinge module 106 of the embodiment is not mounted to the cover 110 bythe screw fastening method, the length of the bracket 106 a of the hingemodule 106 can be longer than half the length of one of the rims 100 aso as to increase the mounting stability between the hinge module 106and the cover 110. In other words, if the length of the bracket 106 a ofthe hinge module 106 becomes longer, the gluing area and range betweenthe bracket 106 a and the cover 110 relatively increase, and thus themounting stability between the bracket 106 a and the cover 110 can beincreased. When the cover 110 is forced, the force can be transmitted tothe hinge 108 via the bracket 106 a and the pivotal portion 106 b, sothat the hinge 108 can rotate together with the cover 110 relative to anobject. So, the width of the portion of the bracket 106 a that isadjacent to the hinge 108 is very important. Because the portion of thebracket 106 a is the interface via which the force is transmitted fromthe cover 110 to the hinge 108, the portion of the bracket 106 a bearslarger force than other portions. If the width of the portion of thebracket 106 a is longer, the mounting capability of the bracket 106 a isalso larger, so as to prevent the defeat that the hinge module 106separates from the cover 110 during the operation of the hinge 108.Generally, the width of the bracket 106 a is directly proportional to adesired torque of the hinge 108 and the width of the bracket isapproximately longer than 25 mm, wherein the width of the bracket 106 ais the width of the end of the bracket that is adjacent to the hinge108. The desired torque of the hinge 108 is the minimum force that thehinge 108 is necessarily loaded during operation.

The cover 110 of the embodiment further includes a reinforcing plate 110a. The reinforcing plate 110 a of the cover 110 can be fixed to theinner side of the cover 110, just like the hinge module 106 does. Thereinforcing plate 110 a can be substantially perpendicular to thebracket 106 a, but the configuration between the reinforcing plate 110 aand the bracket 106 a is not limited to this and can be elasticallychanged according to the requirements of designing or limitations ofmanufacturing. In order to increase the whole stiffness of the displaydevice 100, the reinforcing plate 110 a of the display device 100 andthe bracket 106 a of the hinge module 106 can also be connected to eachother. In other words, the reinforcing plate 110 a and the bracket 106 acan be integrally formed according to the requirements of product designand then fixed to the inner side of the cover 110 to reinforce thestrength of the cover 110. In order to take the weight of the displaydevice 100 into consideration, the reinforcing plate 110 a that is fixedto the cover 110 can be, but not limited to, made from an aluminum plateof which the thickness is 0.6 mm.

When the electronic device has a host housing, the display device 100 ofthe invention can be connected to the host housing by the hinge 108, soas to make the display device 100 to rotate relative to the hosthousing. When the display device 100 covers on the host housing, thereinforcing plate 100 a on the cover 110 of the display device 100 willcorrespond to the palm raise of the host housing, so as to increase thesupporting strength between the display device 100 and the host housingand prevent the display device 100 or the host housing from beingdamaged because users press improper locations.

In another embodiment of the invention, the structures of the inventionare applied to a display device that does not have backlight. Thebiggest difference between the embodiment and the former embodiment isthat the display device of the embodiment can achieve the effect ofevenly emitting light without the backlight module. If the displaydevice that does not have backlight is an OLED (Organic Light-EmittingDiode) display device, the organic light-emitting layer is generallypackaged in the glass module 130 in FIG. 4 to substitute for the liquidcrystal layer 137. Therefore, the panel module only includes the glassmodule 130, and the supporting member on the frame 120 can support thepanel module just by one supporting portion. When the panel module isfixed to the supporting portion of the frame 120, the frame 120 will bethe only one structure that supports the panel module.

According to the foregoing recitations of the embodiments of theinvention, it can be seen that the invention make a panel module and aframe to be fixed to each other to form a display module, so the frameis the only structure that supports the frame. Finally, a cover ismounted to the frame to form a display device. The cover includes ahinge module, and the hinge module can be fixed to the cover andconnects a hinge, so that the hinge can connect the display device and ahost housing to each other. Because the hinge module is fixed to thecover, the thickness of the display device can be greatly reduced, andthe mounting strength of the display device against the rotation of thehinge can be maintained. The display module is also mounted to the coverwithout screws, so the cover does not need to provide space to befastened by screws so as to have a thinner thickness and the displaymodule does not need to be formed screw holes so as to have a largerdisplay region.

It will be apparent to those skilled in the art that variousmodifications and variations can be made to the structure of the presentinvention without departing from the scope or spirit of the invention.In view of the foregoing, it is intended that the present inventioncover modifications and variations of this invention provided they fallwithin the scope of the following claims.
